Product Advantage
1. Black Pipe (Steel Pipe) in Plumbing & Construction
Black pipe, also called black steel pipe, is a type of carbon steel pipe used for gas lines, fire sprinkler systems, and industrial applications.
Advantages:
✅ Durability – Resistant to high pressure and heat, making it ideal for gas and water supply.
✅ Fire Resistance – Non-combustible, often used in fire sprinkler systems.
✅ Cost-Effective – Cheaper than stainless steel or copper pipes for heavy-duty applications.
✅ Strong & Rigid – Less prone to damage compared to PVC or flexible pipes.
✅ No Corrosion (Internally) – Often used for gas lines where moisture is minimal.
APPLICATION
Black steel pipes are commonly used for gas lines, water supply, and fire sprinklers. Proper inspection ensures safety and longevity.
Packing &Shipping
Black square pipes (carbon steel or galvanized) are typically packaged for export/transport in the following ways:
A. Bundle Packaging (Most Common)
Pipes stacked tightly in rectangular bundles.
Secured with steel straps (2–4 straps per bundle).
End protectors (plastic or metal caps) to prevent damage.
Waterproof wrapping (if needed for bulk shipment)).
B. Bulk Loose Loading (For Large Quantities)
Directly loaded into containers or ships (no bundling).
Risk of surface scratches but cost-effective.
